目前迫切需要针对SARS-CoV-2的有效和选择性抗病毒药物。Pfizer开发了PF-07321332(PF-332),这是一种有效的病毒主要蛋白酶(Mpro,3CLpro)抑制剂,可口服给药,目前正在临床开发中。我们在此报告PF-332对四种SARS-CoV-2变异体(VoC)发挥等效的体外活性,并且它可以完全阻止在气液界面生长的原代人气道上皮细胞中α变异体的复制。用PF-332(250 mg/kg,每日两次)治疗叙利亚金仓鼠完全保护动物免受β(B.1.351)和δ(B.1.617.2)SARS-CoV-2变体的鼻内感染。此外,用PF-332治疗SARS-CoV-2(B.1.617.2)感染的动物完全阻止了向未经治疗的共同饲养的哨兵的传播。目前迫切需要针对SARS-CoV-2的抗病毒药物。最有希望的病毒靶点之一是SARS-CoV-2的主要蛋白酶,它对病毒复制至关重要,并且没有人类类似物。在这里,Abdelnabi等人表明,目前处于临床试验中的最有前途的抗病毒药物之一(PF-07321332)可以预防SARS-CoV-2 α,β和δ变体感染,并提供减少传播的证据。
There is an urgent need for potent and selective antivirals against SARS-CoV-2. Pfizer developed PF-07321332 (PF-332), a potent inhibitor of the viral main protease (Mpro, 3CLpro) that can be dosed orally and that is in clinical development. We here report that PF-332 exerts equipotent in vitro activity against the four SARS-CoV-2 variants of concerns (VoC) and that it can completely arrest replication of the alpha variant in primary human airway epithelial cells grown at the air-liquid interface. Treatment of Syrian Golden hamsters with PF-332 (250 mg/kg, twice daily) completely protected the animals against intranasal infection with the beta (B.1.351) and delta (B.1.617.2) SARS-CoV-2 variants. Moreover, treatment of SARS-CoV-2 (B.1.617.2) infected animals with PF-332 completely prevented transmission to untreated co-housed sentinels. There is an urgent need for anti-virals targeting SARS-CoV-2. One of the most promising viral targets is the main protease of SARS-CoV-2, which is essential for viral replication and has no human analogue. Here, Abdelnabi et al. show that one of the most promising anti-virals (PF-07321332), currently in clinical trials, protects against SARS-CoV-2 alpha, beta and delta variant infection and provide evidence of reduced transmission.
